This state of matter has molecules with minimal freedom of movement and speed.
What is a solid?
100
increasing the amount of kinetic energy in an object's molecules will do this.
What is increase temperature / start a phase change?
100
The measurement of the average kinetic energy of all the molecules in an object is known as this.
What is temperature.
100
Explain how swinging on a swing demonstrates the Law of Conservation of Energy.
In that system, the potential energy that starts the movement of the swing converts (or changes into) kinetic energy and it keeps going back in forth until the energy is lost to the environment and the swing stops.

Mr. Eggleston wanted to reheat his three day old Hangry Joe's Chicken sandwich in the airfryer, which uses this type of energy transfer to cook food.
What is convection?
200
In this state of matter, particles have enough energy to slide past one another.
What is a liquid?
200
Dry ice is known to be dry because it undergoes this type of phase change.
What is sublimation?
200
The principle that energy must be transferred from one source to another, and can not be created from scratch.
What is the law of conservation of energy?
200
How do you calculate gravitational potential energy or GPE?
GPE = w x h
GPE = m x g x h
200
This state of matter can transfer energy the most efficiently.
What is a solid?
300
This is the lowest possible temperature at which all molecular motion stops.
What is absolute zero?
300
A temperature scale that bases its degree system upon the phase change properties of water is this.
What is Celsius?
300
A student lists three temperature measurements: 100°F, 100°C, and 100 K. Of the three measurements, Which is the highest temperature?
100°C
300
What is work?
The amount of energy transferred to another object.
300
Mr. Eggleston grabbed a space shuttle tile right out of the 2000 degree Celsius oven. However his hand idd not combust because of this.
What are the properties of insulation?
400
Mr. Eggleston recalls that the outer core of the Earth is liquid, while the hotter inner core is solid. Explain how this is possible.
What is pressure?
Pressure and temperature both contribute to the state of matter.
400
This is a phase change where the liquid left out does not have enough energy to immediately vaporize.
What is evaporation?
400

2 ANSWERS MUST BE GIVEN
Molecules slow down
Molecules get closer together
